Spectral analysis

Identification of spectral properties in analog signals (e.g., the power spectrum).

welch_psd(signal[, n_segments, len_segment, ...])	Estimates power spectrum density (PSD) of a given neo.AnalogSignal using Welch's method.
welch_coherence(signal_i, signal_j[, ...])	Estimates coherence between a given pair of analog signals.
multitaper_psd(signal[, n_segments, ...])	Estimates power spectrum density (PSD) of a given 'neo.AnalogSignal' using Multitaper method
